CONDUCTOR CONNECTER Filed March 19, 1929 Patented Feb. 16, 1932 UNETEDSTATES JOSEPH B. JURAD, OF NEWTON, MASSACHUSETTS CONDUCTOR CONNECTERApplication filed March 19, 1929. Serial No. 348,176.

The invention relates to clips for connecting conductors to terminals,as, for exanr ple, for connecting a jumper wire to the terminal of astorage battery.

The invention will be best understood from the following descriptionwhen read in the light of the accompanying drawings showing one exampleof the invention, while the scope of the invention will be moreparticularly pointed out in the appended claims.

In the drawings Figs. 1 to 3 show a clip constructed according to theinvention in difierent operative positions relative to the terminal ofthe storage battery; and

Figs. 1 and 5 respectively are plan and bottom views of the terminalaccording to Fig. 1.

In the embodiment of the invention illustrated by the drawings, the clipis formed of a spring plate, preferably by stamping it from a sheet ofspring steel and bending it to shape by means of suitable dies, afterwhich it is coated with lead in the usual manner for preventingcorrosion.

As shown, the clip comprises a U-shaped portion 1 having the legs 3 and5, the leg 5 being connected by a curved portion 7 to an arm 9, whilethe leg 3 is connected by a curved portion 11 to a terminal contactingportion 13, the latter directed toward the curved portion 7 As shown,the portion 7 forms a shoulder for contacting with one side of theterminal, while the end of the portion 7 forms an edge for contactingwith the opposite side of the terminal. Preferably, but not necessarily,the end of the portion 13 is of arcuate shape and provided with teeth15, as indicated in Fig. 5, while the end of the arm 9 is reduced inwidth at 17 and formed at its end to present a tubular part 19 (orformed so that it may be readily bent to a tubular shape) for connectingit to a conductor 21.

In practice, assuming the clip is to be at tached to the terminal 23 ofthe storage battery, the clip will be first presented to the terminal asshown by Fig. 1. Then, by forcing the arm 9 downwardly, the parts willsuccessively move into the positions shown by Figs. 2 and 3. Preferably,the top of the U-shaped member and right leg thereof, as viewed in Fig.l, are formed on such curves, relative to the curves presented by theleft leg, curved portion 11, and portion 13, that all the fiexuresubstantially occurs in the former, with the result that when the partsare in the position shown by Fig. 2, the distance between the center ofcurvature 25 of the curved portion 11, and the point of contact 27 atthe opposite side of the clip with the terminal, is greater than whenthe parts are in the position shown by F ig. 3, with the result that theterminal snaps from the position shown by Fig. 2 to the position shownby Fig. 3, and is rigidly secured against removal when in the latterposition, unless removed by forcing the arm 9 upwardly.

It will be observed that, as above described, no sliding action occursbetween the port-ion 13 and the terminal, and that as the parts movesuccessively through the positions shown by Figs. 1, 2 and 3, inattaching the clip, the portion 13 rocks about its point of contact withthe terminal, with the result that the teeth 15 bite into the materialof the terminal, commonly lead, and secure good electrical contact.

It will be understood that wide deviations may be made from theembodiment of the invention herein described without depart-- ing fromthe spirit of the invention.

Claims:

1. A clip for connecting a conductor to a storage battery terminal orthe like comprising an elongated spring member having a terminalcontacting edge at one end portion thereof and a terminal contactingshoulder at an intermediate portion of its length opposed to said edge,said end portion and shoulder being connected by a resilient portionholding them normally in spaced relation, said resilient portion actingto permit said edge and shoulder to grip opposite sides of said terminalin planes transverse to said terminal, and an operating arm at the sameside of said clip as said shoulder.

2. A clip for connecting a conductor to a storage battery terminal orthe like comshoulder.

prising a spring plate member having a generally U-shaped resilientportion, the latter having at the end portion of one leg thereof aterminal contacting portion directed to- Ward the other leg thereof, anoperating arm carried at the end portion of said other leg, and aterminal contacting shoulder portion between said arm and the end ofsaid leg in Which carries said arm.

3. A clip for connecting a conductor to a storage battery terminal orthe like compris= ing a spring plate member having a termi= nalcontacting edge and a terminal contact= ing shoulder, said edge .andshoulder being connected by a resilient portion holding them normally inspaced opposed relation, said shoulder having a relatively smoothsurface or material length whereby said shoulder is readily slidablealong one side of said terminal While said edge is in pivotal contactwith the opposite side of said terminal.
